Possible gravitational lensing?

• by davestringer

  I wondered whether the radio images nearest the centre of this picture are from a galaxy that is behind the infra-red source that they seem to partly surround.

  I had a similar question about lensing, but it was pointed out that if it was "lensed" it should look the same in both "lensed" images. Or something like that. 😃

  After a rather long time, and hoping you two zooites are still around, here's a FIRST contour overlap, on an SDSS image:

  

  At least two hosts seem fairly easily identifiable, and the host of the nice triple on the W border (towards the N) may be easy to find too. Is the N-S almost linear feature in the center the N lobe of strongest source, towards the bottom? Is there a counter-lobe further to the S (overedge)? Maybe some other overlays might help?

  What do you think?

  Boilerplate: SDSS image per http://skyservice.pha.jhu.edu/DR10/ImgCutout/getjpeg.aspx, FIRST (red) contours derived from the FITS file produced using SkyView with Python code described in this RGZ Talk thread. Image center is the center of the ARG image (left; J2000.0).
